Description

Technical Field

[0001] The present invention relates to the field of staplers, and in particular to a stapler mechanism and a stapler with a staple removal function. Background Art

[0002] Staplers are tools that people need to use frequently in daily study and office work. Staplers can be used to bind various papers to prevent them from scattering. The common structure of existing staplers includes an upper cover, a staple channel assembly, and a base. The upper cover and the tail end of the staple channel assembly are rotatably fixed on the base. The staple channel assembly includes components such as a staple channel, a staple pressing plate, and a staple pusher. The staple pusher is placed in the staple channel to limit and push staples to the front end of the staple channel. The tail end of the staple pressing plate is rotatably connected to the tail end of the staple channel, and the front end of the staple pressing plate is aligned with the staple outlet at the front end of the staple channel. When the stapler is used, the user presses the upper cover to drive the staple pressing plate to push out the staples in the staple channel to complete the binding work. The staple pusher can move on the staple channel and is used to push the staples forward and prevent them from moving during binding. The staple pressing plate is pressed down to push the staples out of the staple outlet of the staple channel.

[0003] This type of traditional stapler has problems due to its structural setting. For example, the distance of the stapler outlet is fixed, which is approximately equal to the width of a staple. During use, when there is no paper, the stapler is pressed incorrectly, or the staple is not properly stapled, resulting in the stapler not being able to be smoothly disengaged and getting stuck in the stapler outlet, since the stapler outlet is only a stapler thickness away, the stuck nail will be tightly stuck in the stapler outlet, making it difficult to remove, time-consuming and laborious. Therefore, in view of the problem that staplers are prone to getting stuck and the difficulty in removing stuck staples during normal use, it is necessary to develop a stapler product that is not prone to getting stuck. Utility Model Content

[0004] In order to solve the problem that staplers are prone to getting stuck and the staples are difficult to remove during use, this patent provides the following technical solutions:

[0005] A nail channel mechanism with the function of removing stuck nails includes an inner nail channel, a nail channel and an elastic component. The inner nail channel and the nail channel are hollow structures. The inner nail channel is accommodated in the nail channel. The inner nail channel includes an inner nail channel rear end surface. The elastic component contacts the inner nail channel rear end surface. The elastic component removes the stuck nails by acting on the inner nail channel rear end surface.

[0006] Furthermore, the elastic component is a single component or a combined component, and the number of the elastic components is in the range of 1-6.

[0007] Further, the elastic member has a compressed state and an extended state, and the elastic member is selected from one and / or several of metals, alloys and / or polymers.

[0008] Furthermore, the inner nail channel also includes an inner nail channel hole and a front end surface of the inner nail channel.

[0009] Furthermore, the nail channel includes a blocking surface, a nail channel protrusion, and a nail channel hook. The nail channel protrusion is smaller than the inner nail channel hole, so that the nail channel protrusion is embedded in the inner nail channel hole. Thereafter, the inner nail channel and the nail channel slide relative to each other along the longitudinal axis of the nail channel mechanism within a first range. Changes in the first range affect the size of the nail outlet.

[0010] Furthermore, the nail channel mechanism includes an outer nail channel, which is a fixed cavity structure. The inner nail channel and the nail channel are accommodated in the outer nail channel. The outer nail channel includes a front end face of the outer nail channel and a rear end face of the outer nail channel. There is a second range between the rear end face of the inner nail channel and the rear end face of the outer nail channel, and the elastic component is arranged within the second range.

[0011] Furthermore, the nail channel mechanism includes a nail pusher, one end of which is fixed to the front end surface of the outer nail channel, and the other end of which is fixed to the rear end surface of the outer nail channel. The nail pusher includes a nail pushing block, a push rod and a spring.

[0012] Furthermore, the nail channel mechanism includes a locking portion, and the locking portion includes a locking plate, a locking hook, a rotating shaft, a rotating shaft hole and an unlocking key.

[0013] Furthermore, the locking portion and the nail channel have two matching states: a locked state and an unlocked state. In the locked state, the nail channel hook and the locking hook are engaged with each other, the elastic component is in a compressed state, the inner nail channel and the nail channel have no relative movement, and the first range is a minimum value. At this time, the nail outlet only allows one staple to pass through; in the unlocked state, the nail channel hook is disengaged from the locking hook, the elastic component is in an extended state, the inner nail channel and the nail channel slide relatively along the longitudinal axis of the nail channel mechanism, and the first range is greater than the minimum value. At this time, the nail outlet can remove the staple.

[0014] The utility model also provides a stapler, comprising any one of the above-mentioned staple channel mechanisms.

[0015] The utility model has the following beneficial effects:

[0016] An elastic mechanism is added on the basis of a traditional stapler, and the elastic force of the elastic mechanism generates an outward pushing force on the inner nail channel and the nail channel along the longitudinal axis direction of the nail channel mechanism; at the same time, a nail channel hook is provided on the nail channel, and a locking hook is provided on the locking portion, and the nail channel hook and the locking hook can engage with or disengage from each other, and the matching state of the nail channel hook and the locking hook is changed by an unlocking key, and correspondingly, the locking portion has a locked state and an unlocked state.

[0017] In the locked state, the nail channel hook and the locking hook are engaged with each other, the elastic component is in a compressed state, the inner nail channel and the nail channel have no relative movement, the first range is a minimum value, and at this time the nail outlet only allows one staple to pass through; in the unlocked state, the nail channel hook is disengaged from the locking hook, the elastic component is in an extended state, the inner nail channel and the nail channel slide relatively along the longitudinal axis of the nail channel mechanism, the first range is greater than the minimum value, and at this time the nail outlet can remove the staple.

[0048] The detailed features and advantages of this patent are described in detail in the specific implementation method below, and the content is sufficient to enable any technical personnel in this field to understand the technical content of this patent and implement it accordingly. According to the description, claims and drawings disclosed in this specification, technical personnel in this field can easily understand the relevant purposes and advantages of this patent.

[0049] In order to make the purpose, technical solutions and advantages of this patent clearer, the implementation method of this patent will be further described in detail below in conjunction with the accompanying drawings.

[0050] like Figure 1 As shown, this patent includes a nail outlet 10, a nail channel 20, an inner nail channel 30, an outer nail channel 40, a nail pusher 50, an elastic component 60, and a locking portion 70.

[0051] The staple outlet 10 is located at the front end of the staple channel mechanism and is used for pressing out staples. The width of the staple outlet 10 in this embodiment changes with the change of the first range, and the minimum value of the first range is about the width of a staple. The inner staple channel 30, the staple channel 20 and the outer staple channel 40 in the staple channel mechanism are all similar to an upper open cavity structure. The staple channel 20 is sleeved in the outer staple channel 40, and the inner staple channel 30 is accommodated in the staple channel 20 and the outer staple channel 40. The outer staple channel 40 is fixed, and the inner staple channel 30 and the staple channel 20 can move forward and backward along the longitudinal axis direction of the staple channel mechanism, and relative sliding can occur between the inner staple channel 30 and the staple channel 20 within the first range. The elastic member 60 is provided in the cavity formed by the inner staple channel 30 and the outer staple channel 40, and the cavity can change size along the longitudinal axis direction of the staple channel mechanism, and the size of the cavity change is the second range. One end of the elastic member 60 contacts the inner staple channel 30, and the other end contacts the outer staple channel 40. The locking portion 70 is located at the end of the staple channel mechanism and has two states: a locked state and an unlocked state. When the locking portion 70 is in the locked state, the staple channel 20 and the inner staple channel 30 do not move relative to each other, and the staple outlet 10 only allows one staple to pass through; when the stapler is stuck, the locking portion 70 is adjusted to be in the unlocked state, and at this time, the elastic member acts on the inner staple channel 20, so that the staple channel 20 and the inner staple channel 30 slide relative to each other along the longitudinal axis direction of the staple channel mechanism, thereby removing the stuck staple.

[0052] like Figure 2 As shown, the staple channel mechanism includes a staple pusher 50 located in the inner staple channel 30, which is used to push the staples arranged in the inner staple channel 30 toward the staple outlet 10. The staple pusher 50 includes a staple pusher block 51, a push rod 52 and a spring 53. The staple pusher block 51 is a long plate with two fixing rings at the bottom, which is arranged below the front end surface 41 of the outer staple channel 40. The spring 53 is wound on the push rod 52. One end of the staple pusher 50 passes through the two fixing rings and is fixed to the front end surface 41 of the outer staple channel, and the other end of the staple pusher 50 is fixed to the rear end surface 42 of the outer staple channel. There are sufficient cavities around the staple pusher 50 to accommodate the elastic member 60.

[0053] like Figure 3 As shown, the nail channel mechanism includes a nail outlet 10, a nail channel 20, a blocking surface 21, a nail channel protrusion 22, a nail channel hook 23, an inner nail channel 30, an inner nail channel front end surface 31, an inner nail channel hole 32, an inner nail channel rear end surface 33, an outer nail channel 40, an outer nail channel front end surface 41, an outer nail channel rear end surface 42, a nail pusher 50, a nail pusher block 51, a push rod 52, a spring 53, an elastic component 60, a locking portion 70, a locking plate 71, a locking hook 72, a rotating shaft 73, a rotating shaft hole 74, and an unlocking key 75.

[0054] The inner side of the vertical surface at the front end of the nail channel 20 is a blocking surface 21, which can resist the stapler and fix its position. Two nail channel hooks are provided at the rear of the top of the side of the nail channel 20, and the bottom plane of the nail channel 20 contains nail channel protrusions 22 protruding upward. Specifically, in this embodiment, the number of nail channel protrusions 22 is 3. The inner nail channel 30 includes inner nail channel holes 32 on its bottom surface, and the number of the inner nail channel holes 32 is the same as that of the nail channel protrusions 22. When the inner nail channel 30 is matched with the nail channel 20, the nail channel protrusions 22 can extend from the inner nail channel holes 32 and can slide forward and backward in the inner nail channel holes 32 along the longitudinal axis direction. Through the matching of the nail channel protrusions 22 and the inner nail channel holes 32, the range of movement of the inner nail channel 30 relative to the nail channel 20 is limited, and the range is the first range. The first range determines the range in which the staple outlet 10 can change. The inner nail channel 30 has an inner nail channel front end surface 31 perpendicular to the longitudinal axis at its front end, and an inner nail channel rear end surface 33 at the rear end. The front end surface 31 of the inner nail channel and the blocking surface 21 of the nail channel 20 form a boundary of the nail outlet 10 in the longitudinal axis direction, and determine the width of the nail outlet 10 in this direction.

[0055] The nail channel mechanism also includes an elastic member 60. In this embodiment, the elastic member 60 is a spring made of stainless steel. The elastic member 60 has two states: a compressed state and an extended state. When the elastic member 60 is in the compressed state, it has a tendency to extend toward both ends. When the elastic member 60 changes from the extended state to the compressed state, it is necessary to apply an extrusion force to the elastic member 60, and one or more positions are required to maintain the compressed state of the elastic member 60. In this embodiment, the nail channel hook 23 and the locking hook 72 are engaged with each other to maintain the elastic member 60 in the compressed state.

[0056] like Figure 4 , Figure 5 As shown, the nail channel mechanism also includes a locking portion 70, which includes a locking sheet 71, a locking hook 72, a rotating shaft 73, a rotating shaft hole 74 and an unlocking key 75. The front end of the locking portion 70 is composed of two locking hooks 72, and the locking hooks 72 and the nail channel hook 23 can be engaged with or disengaged from each other. The locking portion 70 has two sheet-like extension plates, each of which is provided with a rotating shaft hole 74, and the rotating shaft hole 74 is used to connect the rotating shaft 73. The rear end of the locking portion 70 is provided with an unlocking key 75, which can be lifted. It can be understood that when the unlocking key 75 is lifted, the locking hook 72 and the nail channel hook 23 are in a state of being disengaged from each other, which is the unlocking state of the locking portion; when the unlocking key 75 is in the normal position, the locking hook 72 and the nail channel hook 23 are in a state of being engaged with each other, which is the locking state of the locking portion. By locking the closed state of the stapler, the working state is made more stable.

[0057] The coordination of the components of the nail channel mechanism in the locked state. The nail channel 20 is pushed backward along the longitudinal axis of the nail channel mechanism, and the nail channel 20 pushes the inner nail channel 30 to move backward together through the nail channel protrusion 22. At this time, the nail outlet 10 is reduced synchronously with the first range, and the second range is also reduced. The nail channel hook 23 moves backward along the longitudinal axis until the elastic member 60 changes from the extended state to the compressed state, and the inner nail channel 30 stops moving backward. At this time, the nail channel 20 and the inner nail channel 30 are both in the final position, and the nail channel protrusion 22 also abuts against the rear end of the inner nail channel hole 32. The nail channel hook 23 and the locking hook 72 are in a mutually engaged state, and the unlocking key 75 at the tail of the locking plate 71 returns to the locked state. In this way, under the joint restriction of the nail channel protrusion 22, the nail channel hook 23 and the locking hook 72, the position of the inner nail channel 30 relative to the nail channel 20 is fixed, so that the length of the nail outlet 10 along the longitudinal axis direction of the nail channel structure is also fixed, which is approximately equal to the thickness of a staple.

[0058] If a staple jam occurs and the staple stuck in the staple outlet 10 needs to be removed, the unlocking key 75 at the rear of the locking plate 71 is lifted, and the staple channel hook 23 and the locking hook 72 are separated from each other. Under the elastic action of the elastic mechanism 60, the staple channel 20 and the inner staple channel 30 automatically pop out along the longitudinal axis of the staple channel mechanism. At this time, since the staple channel protrusion 22 is still moving forward in the inner staple channel hole 32, the staple channel 20 cannot drive the inner staple channel 30 to move forward. When the front end surface of the staple channel protrusion 22 contacts the front end surface of the inner staple channel hole 32, the staple channel 20 starts to drive the inner staple channel 30 to move forward. It can be understood that, due to the asynchronous movement of the staple channel 20 and the inner staple channel 30 at the beginning, the width of the staple outlet 10 along the longitudinal axis of the staple channel mechanism increases and is greater than the thickness of a staple. At this time, the staple channel mechanism is in an unlocked state, and accordingly, the stuck staple can be easily removed from the staple outlet 10.

[0059] In the specification of this patent, terms indicating directions, such as "front", "rear", "up", "down", "left", "right", "side", "top", "bottom", etc., are used to describe various example structural parts and components of this patent, but these terms are used here only for the purpose of convenience of description and are determined based on the example orientations shown in the drawings. Since the embodiments disclosed in this patent can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0060] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this patent will not further describe various possible combinations.

[0061] In addition, the various implementation methods of this patent can be combined arbitrarily, as long as they do not violate the concept of this patent, they should also be regarded as the contents disclosed by this patent.
